Devfreq framework supports 2 modes for monitoring devices. Use delayed timer as default instead of deferrable timer in order to monitor the GPU status regardless of CPU idle.
Signed-off-by: Lukasz Luba lukasz.luba@arm.com --- Hi all,
I've missed the Lima driver while working on Panfrost patch for fixing the issue with default devfreq framework polling mode. More about this and the patch, can be found here [1].
